Application filed. October 2, 1920. Serial No. 414,168.

To all whom it may concern Be it known that I, HARRY'D. KOSTEN- BAUDER, a citizen of the United States, re-' chutes, slate and the like is, as a rule, picked out by hand, the coal passing on to carriers or to a dump or'loaded into cars, while the slate is thrown'into a chute, and passes to what is called a culm bank;

In picking out the slate, thereis considerable coal picked out therewith, in fact.

some coal sticks to the slate, hence, it is the purpose of the present invention to separate this coal from the material of the culm bank.

The material of the culm bank is first passed through crushers, after which it is. the purpose to pass this crushed material through the present form of mineral or coal separating jig, whereby the coal-therein .may be separated from the slateyin order top ments 4 and the compartment 5, whereby afford considerable saving.

The present invention further embodies thepurpose, whereby the material from the culm is'first deposited in a perforated pan, there being a casing for containing-a large quantity ofv water, and means for causmg' a pressure of water upwardly through the perforated pan, in order to cause the coal or' lighter material to come to the. top and over-flow the pan andbe carried off by suitable conveying means, while the slate or heavier material will automatically and periodically pass offfrom .belowinto a chute, and then to a suitable convey'er.

It is afurther aim to provide means for periodically dumping. or carrying off the shite, according-tome weight thereof on a, suitable trap, which is counterbalanced by,

9 downward movements of the pressure creatme'ans of a gravity member.

A still further purpose to afford plungers including check valves, forcre'atinga.

While the design and construction at present illustrated and set forth is deemed the right to these changes is claimed, propreferable, it is obvious that as a result of a reduction of the invention to a more practical form for commercial purposes, the invention may be susceptible of changes, and

vided they are comprehended within the scope of what is claimed.

The invention comprises further features and combination of parts, as will be hereinafter set forth, shown in the drawings and claimed.

In the drawings I Figure 1 is a vertical sectional view through the improved coal or mineral separating jig constructed in accordance with theinvention.

Fig. 2 is a plan view of the same.

Fig. 3 is a verticalsectional view on line 33 of Fig. 1. v

Fig. 4 is a sectional view on line Mfof Referring to the drawings, 1' designates a suitable jig casing, in which partitions 2 and 3 are. arranged, thereby dividing the casing into lunger receiving compartments 1 and a per orated separating pan receiving compartment 5. Aslshown in Figs. 1 and 3 the partition 2 is provided with openings of communication 6 between the comparta pressure of water may pass from the compartments 'into the compartment 5. ,Rising upwardly from the ends of the jig casing are the frames 7, in'bearings 8 of the tops of which a rotating driven shaft 9 is mounted. This shaft is provided with eccentrics 10 having eccentric straps 11, each of which is provided with eccentric pitman rods 12.

Adapted to reciprocate in the compartments 4 are pressure creating plungers 13, which have elongated openings 14. Hingedly mounted at 15 to the under-surfaces of the pressure creating plungers are flap check valves 16, adapted for controlling the water through the openings 14. For example the check valves are adapted to close on the ing plungers .13, and open on the upward movements, the purpose being to create a pressure of the liquid in. the compartment 5 on the down strokes of the plungers and Patented Nov. 1, 1921.

to. avoid a suctionin the compartment 5 on theupward strokes of theplungers'.

Oppositely disposedrods 17 are pivotally connected at 18 to the links 19, each of which in turn is connected at 20 to a pitman 12. The lower ends of the oppositely disposed rods 17 terminate in a casting 21, which comprises the diverging bars and the horizontal plates 22. The plates 22 are fastened by bolts like 23 to the pressure creat-- ing plungers, so that the plungers may move evenly in the compartments 4. It is to be noted that. the heads of the bolts 23 are countersunk in the under-faces of the plungers, thereby permitting check valves tocompletely close on the downward strokes of the plungers.- It is obvious that when power from any suitable source (not shown) is transmitted to the shaft 9, reciprocating movements will be imparted to the plungers, hence causing a liquid pressure to be created in the chamber or compartment 5. This pressure causes the water to percolate upwardly from the perforations 25 of the stationary separating plate 26, which is mounted or secured in any suitable manner in the upper part of the compartment or chamber 5. Upon this platethe material from the culm bank is first deposited. One end of the pan or plate 26 hasan inclined portion 27,which causes the material to feed toward the other end of the pan or plate. The other end of the pan or plate terminates in an upright wall 28 and adjacent the upper edge of this wall a suitable coal discharge chute 29 is arranged. This chute is designed to take the over-flow of the coal or lighter material, which iscausecl to rise to the top of the material, due to the pressure of water under the pan. The end of the pan or plate adjacent the wall 28 has an opening 30, and arranged therein is a trap 31,]the fulcrum of which is designated by the numeral 32. Rising upwardly from the upper edges of the opposite walls of the compartment 5 are standard 33, and pivoted thereon at 34 are counter-balancing rods 35. Theserods have pivoted thereto as at 36, rods 37, which.

in turn are pivoted at 38 to the trap 31. Adjustable gravity members 39 are threaded on the counter-balancing rods, for maintaining the trap, normally closed. The gravity members may be otherwise mounted upon the rods, a for instance slidably, and if so mounted they may be held in different positions by notches (not shown). The trap is designed to open periodically at 40, and adjacent where the trap opens a suitable slate chute or discharge 41 is provided." When the trap 31 opens, it extends in a line with the bottom of the slate discharge chute 41. -The trap opens, when the weight ofthe slate thereonoverbalances the gravity member 39.

. Projecting'from the separator jig casing i are beams 42 and 43 and the intermediate beams 44, and mounted in bearings of these projecting beams are shafts 45, 46 t ey;

which carry the sprockets 48 and 49, 50 and 51. Endless conveyer chains 52 having conveyer buckets 53 pass about the sprockets 48 and 50. The coal. chute'or discharge 29 empties the coal direct into the elevator buckets 53. Endless elevator or conveyer I chains 54 pass about the sprockets 49 and 51, and also have conveyer or elevator buckets 55. The slate chute or discharge .41 has a transversely disposed portion or chute 56, passing along one end of-the separator jig casing, and is disposed on an inclined plane for the purpose of causing the discharge of the'slate into the buckets or receptacles 55. Theslatematerial empties from the buckets 55 .on their downward.

.In the operation, the 'separator'jigcasing is first filled with a'suiiicient quantity of water, after which the material from the culm bank is deposited into the perforated separator pans Power is then transmitted to the shaft 9, causing reciprocatin'gimovements to be imparted to the plungers 13.

Upon downward movements of the plun! gers the pressure of the liquid or water is created in the chamber or compartment 5, causing the water to thoroughly percolate through the perforations of the. separator coal to cars (not pan, thereby causing the coal or lighter material tocometo the surface, and then overflow the end wall 28 and pass off through the coal discharge chute 29. The slate being the heavier material settles to the b0ttom,'an d when a sufiicient amount thereof becomes located on the trap, its weight will overcome the gravity member 39- and cause the lot trap to open. The slate willthen' pass off through the chutes 41 and 56. to the slate elevator. The check valves of the'plungers are not only to preventa suction and a return of the water 1 into the compartments '4, but

also prevent suction on the materialto be separated, hence preventing the lighter material or coal from beingdrawn to the bot-I tom of the pan. .On the downward strokes of the plungers, the check valves automatically close, causing the pressure of water or liquid in the compartmentb, and hence causing the lighter material to come to the I surface. It isto'be notedthat'by the ro vision of the openings 14, the water or liquid" is allowed to flowbeneath the plungers upon the upper strokes of the plungers, sothat on causing the agitation of the thec'om 0 pan causes the impurities or heavier materlal such as slate and the like a much better opportunity to separate from the lighter material or coal. By the pan being stationary, and the trap being movable as illustrated and described, the trap will operate automatically and more successfully than other devices for the same purpose, and furthermore the slate will be more efliciently separated. When the trap is closed, it prevents the escape of the water pressure, otherwise causing the water to pass through the perforations of the pan, causing the agitation of thematerial, and the over-flow of the coal or lighter material.

The invention having been set forth,what

is claimed as useful is In a mineral separator, a jig casing provided w1th a pan recelv ng separating compartment, a perforated pan in said compartment provided with an opening at one end, one edge of said opening having a depending wall, a chute engaging through the wall of the casing and communicating with said compartment, a trap mounted for pivotal movement in said opening for closing the same, said chute communicating With said compartment at a point opposite and below the depending wall, whereby the trap may assume an inclined position in alinement with the bottom of the chute when overbalanced by the weight of the mineral thereon, so that one edge of the trap may assume a position even with the upper surface of the pan, gravity means for holding the trap normally closed, and a second chute for carrying of]? the lighter particles of the mineral. In testimony whereof I hereunto afiix my signature.
